Hi Viesturs, I have just been implementing something a little similar on my mill - at least, you can achieve what you want in a similar way. I have the mill set up as a normal 3-axis mill with home/limit switches at one end of each axis. What I wanted to set up now was a configuration where I can use my rotary axis on the middle of the table as a 'C' axis, i.e. with its spindle parallel to the milling spindle. To make setting up the jobs easy, I wanted the milling spindle to 'Home' to the exact centre of the rotary axis spindle. It turns out to be quite easy to do.... just set the HOME_OFFSET to a distance equal to half the axis travel and HOME_POSITION to 0.00. In my case, the X and Y axes rapidly move to the end of their travel until they hit the home switch, back off it then slowly onto the switch again to get exact position and finally rapidly move to the central position and set the axis display to 0.000 . In your case, you could put either a mechanical or optical switch on one side of each axis at 50 degrees from centre and set HOME_OFFSET to 50 and HOME_POSITION to 0.000 . If the switch is a little off the exact position, it doesn't really matter as you can easily correct the error by adjusting the HOME_OFFSET value until your spindle/torch lies truly vertical.
